Description
Technical field
A kind of fixture is the utility model is related to, specifically a kind of improved automotive hub turning attachment.
Background technology
In automotive hub lathe machine adds production, automotive hub need to position clamping Vehicle Processing, common hydraulic lathe fixture
Because hydraulic coupling is excessive, it can shine into chuck jaws and damage often.
The content of the invention
A kind of improved automotive hub turning attachment, including centralized positioning pin, wheel lip positioning, clamping jaw, support, bearing pin, even
Connect screw, connecting screw, ejector pin, extension spring, three leaf dish cams, guide pin bushing, rotary gear shaft, rack push rod, cylinder, chuck body frame
Frame.
Centralized positioning pin is placed in chuck body center, the same pitch circle that wheel lip alignment pin is placed in chuck body
On, clamping jaw is connected on support by bearing pin, and support is cast as one with chuck body framework, and connecting screw is by connecting screw
Clamping jaw lower end is fixed on, ejector pin is placed in guide pin bushing, and clamping jaw bottom is connected in chuck body framework by extension spring, and extension spring keeps clamping jaw
Open configuration is not in during clamping workpiece.Three leaf dish cams are placed in rotary gear shaft, and rotary gear shaft is placed in chuck body framework
In guide pin bushing, rack push rod is connected with cylinder.
The utility model connects rack push rod band moving teeth using cylinder piston rod band carry-over bar push rod linear motion by tooth
Axis of rotation is taken turns, the reducing feature of cam contact surface is driven by the horizontal rotation of three leaf dish cams, and three leaf dish cams are changed
Enter to add spacing preiection part, prevent three leaf dish cams from excessively rotating, to complete ejector pin ejecting function, by clamping jaw in bearing pin
In rotation, clamping jaw clamp automotive hub.
The utility model can save manpower and material, can further improve production efficiency.

Embodiment
A kind of improved automotive hub turning attachment, including centralized positioning pin 2, wheel lip positioning 3, clamping jaw 4, support 5, bearing pin
6, connection screw 7, connecting screw 8, ejector pin 9, extension spring 10, three leaf dish cams 11, guide pin bushing 12, rotary gear shaft 13, rack push rod 14,
Cylinder 15, chuck body framework 16.
Centralized positioning pin 2 is placed in chuck body center, the same pitch circle that wheel lip alignment pin 3 is placed in chuck body
On, clamping jaw 4 is connected on support 5 by bearing pin 6, and support 5 is cast as one with chuck body framework, and connecting screw 8 passes through connection
Screw 7 is fixed on the lower end of clamping jaw 4, and ejector pin 9 is placed in guide pin bushing, and the bottom of clamping jaw 4 is connected in the framework of chuck body 17 by extension spring 10,
Extension spring 10 keep clamping jaw 4 not clamping workpiece when be in open configuration.On three leaf dish cams 11 are placed in rotary gear shaft 13, gear turns
Axle 13 is placed in chuck body framework guide pin bushing 12, and rack push rod 14 is connected with cylinder 16.
The utility model is moved along a straight line using the piston rod of cylinder 15 band carry-over bar push rod 14, and rack push rod 14 is connected by tooth
Drive rotary gear shaft 13 to rotate, the reducing feature of cam contact surface is driven by the horizontal rotation of three leaf dish cams 11, and to three
Leaf dish cam 11 is improved and adds spacing preiection part, prevents three leaf dish cams 11 from excessively rotating, and work(is ejected to complete ejector pin 9
Can, by rotation of the clamping jaw 4 in bearing pin 6, clamping jaw 4 clamps automotive hub 1.
When the not clamping workpiece state of clamping jaw 4, extension spring 10 makes clamping jaw 4 be in open configuration.Utilize centralized positioning pin 2, wheel
Automotive hub 1 is placed on fixture by the positioning of lip positioning 3, then opens the such rack push rod 14 of cylinder 15 using pedal pneumatic switch
Linear motion drives rotary gear shaft 13 to rotate, and the then horizontal rotation of three leaf dish cams 11 drives the special-shaped cam pitch circle of cam 3 to become
Greatly, outwards ejection contacts connecting screw 8 to ejector pin 9, passes through rotation of the clamping jaw 4 in bearing pin 6, and clamping jaw 4 clamps automotive hub 1.
After processing automotive hub 1 is completed in Vehicle Processing, the such rack push rod 14 of cylinder 15 is closed using pedal pneumatic switch
Linear motion drives rotary gear shaft 13 to rotate, and the then horizontal rotation of three leaf dish cams 11 drives the special-shaped cam pitch circle of cam 3 to become
Small, by the pulling function of extension spring 10, by rotation of the clamping jaw 4 in bearing pin 6, clamping jaw 4 unclamps automotive hub 1 and completes one action
Circulation.
